The aim of this study is to develop and evaluate a high-performance liquid cooling vest utilizing microchannel technology tailored for military infantry personnel operating in extreme heat. The system seeks to enhance thermal regulation, improve user comfort, and reduce the physical burden compared to conventional cooling systems by integrating dense arrays of hollow polypropylene microtubes into a wearable design.
1- Adopt microtube-based cooling systems as a viable alternative to traditional macro systems, offering superior skin contact, higher cooling performance, and reduced weight and water consumption.
2- Prioritize lowering the inlet fluid temperature in design considerations, as it significantly impacts cooling performance more than flow rate.
3- Utilize polypropylene microtubes for their lightweight structure, quiet operation, reduced vibration, and lower susceptibility to blockage or leakage.
4- Implement automated manufacturing processes to enable scalable, cost-effective production of microtube-based cooling garments for military use.
5- Incorporate advanced human body thermoregulation models in system design and evaluation to more accurately predict physiological responses and optimize performance.
6-Further investigate pressure optimization strategies to address the slightly lower mechanical efficiency due to increased pressure drop in microchannel systems.
